Ginkgo Biloba Extract

Active Ingredients: Flavone glycosides, Terpene lactones (including ginkgetin)

Specification: Flavone glycosides: 24%, Terpene lactones: 6%

Standard: GMP, ISO9001, HACCP, Kosher, HALAL

Description:

Ginkgo Biloba Extract is a standardized botanical ingredient obtained from the leaves of Ginkgo biloba L., a tree species known for its exceptional longevity and unique evolutionary status. As the only surviving member of the Ginkgophyta division, Ginkgo biloba has been extensively studied and widely used in traditional and modern applications, making Ginkgo Biloba Extract one of the most recognized botanical extracts in global markets.

Produced through controlled solvent extraction, Ginkgo Biloba Extract is standardized to contain 24% flavone glycosides and 6% terpene lactones. This standardized composition ensures stable quality and predictable performance in formulation. The product appears as a brown fine powder with uniform particle size, allowing easy incorporation into capsules, tablets, powders, and functional food systems.

From a compositional perspective, standardized Ginkgo Biloba Extract is defined primarily by two complementary component groups: flavone glycosides and terpene lactones. The flavone glycoside fraction represents a complex mixture of flavonoid compounds naturally present in ginkgo leaves, including various mono- and biflavonoids, which together form the extract’s characteristic antioxidant profile. Terpene lactones, a structurally distinct group unique to Ginkgo biloba, constitute the second core fraction and are closely associated with the extract’s microcirculatory relevance. The widely adopted specification of 24% flavone glycosides and 6% terpene lactones reflects a long-established balance derived from pharmacopoeial standards and formulation practice, ensuring consistent composition, reproducibility, and broad regulatory acceptance across global markets.

Ginkgo Biloba Extract is widely associated with circulation-focused and cognition-related formulations. The flavonoid components of Ginkgo Biloba Extract contribute antioxidant properties, while terpene lactones are studied for their role in supporting normal microcirculation. For this reason, Ginkgo Biloba Extract has long been used in products designed for brain health concepts, vascular support, and healthy aging.

Due to its broad application history and well-documented botanical profile, Ginkgo Biloba Extract remains a core ingredient in dietary supplements, functional foods, and pharmaceutical raw material systems worldwide. Manufacturing under GMP conditions and compliance with international standards allow this Ginkgo Biloba Extract to meet regulatory and quality expectations in multiple markets.

Ginkgo Biloba Extract — FAQ Section

6. What are flavone glycosides and terpene lactones in Ginkgo Biloba Extract?

Flavone glycosides and terpene lactones are the two principal standardized component groups in Ginkgo Biloba Extract. Flavone glycosides represent a group of flavonoid compounds responsible for the antioxidant profile of the extract, while terpene lactones are a distinct class of compounds unique to ginkgo that are closely associated with microcirculatory support. Together, these two groups define the characteristic composition and functional profile of standardized Ginkgo Biloba Extract.

7. Is ginkgetin a separate active ingredient from flavone glycosides?

No. Ginkgetin is a specific biflavonoid naturally present in ginkgo leaves and belongs to the flavonoid fraction of Ginkgo Biloba Extract. It is part of the broader flavone glycoside/flavonoid system rather than a separate standardized category. In commercial Ginkgo Biloba Extract, ginkgetin is typically not quantified individually but contributes to the overall flavonoid profile.

8. Why is “24% flavone glycosides and 6% terpene lactones” considered the standard specification?

The specification of 24% flavone glycosides and 6% terpene lactones is based on long-established pharmacopoeial standards and the composition used in the majority of clinical and formulation studies on Ginkgo Biloba Extract. This ratio represents a balanced and reproducible profile that has been widely adopted by the industry for quality control, formulation consistency, and regulatory acceptance.

9. Are higher flavone or lactone contents always better in Ginkgo Biloba Extract?

Not necessarily. Increasing flavone glycosides or terpene lactones beyond established standards does not automatically improve formulation performance and may affect stability, safety margins, or regulatory acceptance. The 24% flavone glycosides and 6% terpene lactones specification is considered an optimal balance that ensures consistent quality and broad compatibility across dietary supplement, food, and pharmaceutical applications.
